At present, Shanghai is constructing the LED (semiconductor lighting) demonstration site of Yuyuan. The overall lighting renovation project in the core area of ​​Yuyuan is jointly undertaken by Shanghai Semiconductor Lighting Engineering Technology Research Center and Shanghai Municipal Appearance Administration and Huangpu District People's Government.
Prior to the actual investigation, the original architectural lighting system did not reflect the details of the ancient buildings. Some places that looked elegant during the day were too vulgar at night, and the details were lacking, including light color, glare, lamp position and form. Wait. In order to show the architectural style, improve the lighting quality, and make the traditional buildings of Yuyuan shine, the research team decided to adopt LED as a modern lighting method. After the lighting system is modified, it can save more than 30% energy and the color level is more abundant. The application of LED lighting system will form a new point of view, and the night view of the Yuyuan area will become more attractive and attract more citizens.
LED is a new type of solid-state light source that has developed rapidly in recent years, and has shown remarkable energy-saving effects in the field of special lighting. It has unique advantages in ancient architectural lighting: safety, energy saving, stability and flexibility, environmental protection, and quick response.
In the process of this lighting renovation, traditional lanterns such as metal halide lamps and sodium lamps in Yuyuan Garden were replaced by LEDs. Shanghai Semiconductor Lighting Engineering Technology Center has successfully developed three kinds of LED lamps for this lighting transformation: linear LED mini-projection/flooding lights, ultra-small LED spotlights. The linear LED mini-projection/flooding lamp is suitable for night illumination of ancient building roofs and walls in the Ming and Qing Dynasties. The ultra-small LED spotlights are suitable for the decorative lighting of ancient buildings and pavilions, and can achieve the effect of seeing no lights.
